The big picture

What is television but the deft arrangement of red, green, and blue? At a late January event sponsored by Sony, British artist Paul Cocksedge made the point that no matter how fancy and feature-filled the TV set, red, green, and blue lights remain encoded in its DNA. His installation at the Tramshed gallery in London juxtaposed a simulation of the basic elements of a TV pixel—in the form of colored spotlights converging on a single white spot—with some advanced new Sony sets, including one with an organic LED screen and another as thin as a CD case.
